What should a normal human being’s daily water consumption be?
Our body looses water on a continuous basis due to digestion, transpiration and respiration. As a general principle, lost quantity of water has to be replaced.
Daily quantity of water we should have equals to nearly 1/36th of our body’s weight. For example, minimum daily water requirement of someone of 72 kg is 2 liters. Any adult should drink at least 1.5 liter of water per day, if we would ever assume that aforementioned quantity would be received trough various foods. This amount is the quantity recommended for adults by dietitians.
Besides, pregnant women should consume even more water, for, pregnant women’s water requirement is higher when we consider water transfer between the future mother and fetus and at least 1 liter water consumption of any fetus per day. Women do carry nearly 8 liters of more water during pregnancy.    

What are advantages of calcium and magnesium contained in water? 
Calcium is the mineral included in main structure of bones and which makes them stronger. However, duties of this important mineral required every day by our body are not limited to this. Regular heart beat, regular operation of blood coagulation system, regular operation of neurological system and regular functioning of muscles do also require calcium’s assistance. Calcium plays key-role on regular operation of the organism. Nearly 99% of calcium the body has is accumulated on bones and teeth. Balance of 1% is observed in the blood and soft tissues. Though this 1% might be considered unimportant, it has got vital importance, for; aforementioned impacts are based on this minimal quantity available in the circulation.
Magnesium strengthens bones and a tooth, provides muscle relaxation, reduces syndrome indication prior to menstruation; and is very important for cardiovascular muscles and neurological system. It is charged with energy generation, and has also got some auxiliary duties on various organic operations.

Does magnesium have lower and upper limits?
Magnesium is not included to assessments in the new Regulations, and has not any lower or upper limit. 
Waters which contain more Magnesium are harder, whereas Magnesium content is lower in soft waters. However, palatal delight and preferences change according to national culture.
Waters whose Magnesium content is lower are easily discharged from the body, and may be more compatible for those who have kidney problems. 

What is Ph? 
Ph is a logarithmic measure which indicates the water’s acidic or alkaline state, and describes H+ ion concentration in the solution. Distilled water is stable in terms of H+ and OH- ions, and its Ph value is “7”. Ph value can be measured according to electric potentials of H+ ions or with color indicators (e.g. phenolphthalein). For example, number of hydrogen ions is higher in acidic liquids and their Ph value is less than “7”, whereas alkaline liquids do have higher number of hydroxyl ions and their Ph value is higher than “7”.         
Environment is acidic if Ph is smaller 7 and is alkaline if greater than 7.
Ph value is recommended to be 6.5 to 9.5

What is conductivity?
Conductivity is an electrical value created by totality of minerals and mineral salts contained in water. Conductivity increases parallel to the increase of quantities of minerals and mineral salts available in water.

What does hardness degree mean in water?
Waters all around the world are evaporated and stocked in clouds and return back to the earth as rainwater. 
They decompose carbon dioxide available in the atmosphere on the way back and become a little bit acidic. This acidic rainwater is decomposing from various rock stratifications and aquifers the calcium carbonate. Hard waters are those who carry on these minerals. Hardness degree of any water is related to decomposition degree of calcium carbonate in water in question. Similar chemical reactions are valid too for sulfite, silicic acid salt and iron; however decomposed calcium carbonate is the most important element affecting hardness degree of any water. 

Why should I prefer bottled (packaged) waters?
Bottled (packed) waters should be clean and hygienic at the original spring state, due laws and regulations. You can drink such waters directly from the spring, without any additional treatment. Bottled (packed) water means the presence of the Ministry of Health’s license, which is delivered pursuant to very rigorous provisions of the Ministry of Health’s Regulations, and availability of reliability in terms of absence of any public health risk. Running waters have in general an unpleasant odor and savor due presence of disinfectants such as chlorine. Bottled (packed) waters do not have such a disadvantage.

How should I use/store bottled (packaged) water?
Bottled waters should be conserved in fresh (15 to 25 Celcius degrees), dark (away from sunshine), and dry (less than 50% humidity) places. Do not place bottled water next to general heating panels and do not expose them to direct sunshine. Please be careful to best before date and ensure conservation conditions while you consume your bottled water.

On what conditions should we conserve bottled (packaged) waters?
They should be conserved in fresh (15-25 Celcius degrees), dark (away from the sunshine), and dry (less than 50% humidity) places. Besides, pay enough attention to keep them as much as possible off chemical substances, detergents, cleaning substances, gasoline and similar substances; for, water is a pure substance and has the potential to attract and accumulate odors available in the environment, and which we cannot even perceive.

What are the factors affecting bench life (physical life) of bottled (packaged) waters?
-Air permeability level of water packaging: bottle packaging type and thickness specifies air permeability, and this determines as the result, the packaging’s protection capacity against odors generated on external environment. PET and poly carbonate bottles, are more sensible, due to their molecular structure, to external environment odors.
-Water’s mineral concentration (hard or soft water): soft waters, due to their low mineral concentration and high purity, attract external environment odors more than hard waters.  
-Stocking and conservation conditions: water would get deteriorated (green aspect, residues) in coming days, if proper environment conditions (clean, dry, odorless places deprived of direct sunshine) are not provided.

What is ideal consumption temperature for water?
Water’s normal temperature is from 5 to 20 Celcius degrees, and temperatures higher than 20 Celcius degrees are not recommended, due high risk of bacteria generation in water.

What is consumption life of opened PET product?
Bottled (packed) products over 5 liters should be consumed within maximum 3 to 4 days, and others during the same day, due presence of mouth contact.

How can I recognize the quality of water I consume?
You should first of all control whether the water you consume has got Ministry of Health’s license or not, and whether label on packaging contains or not license date and number. Pay due care that packaging of water you buy has brand-name on four different locations, to say, on label, on packaging body (embossed), on safety band and on the cap. Besides, label info should definitely include type and nature, production plant address, treatments done to water, and parameters the water contains. In addition, production/bottling and best before dates, and series and lot numbers, and enterprise logo should appear in embossed style on carboy packaging. Due attention paid to safety band proves that you are the first to open the bottle.
